Figure 2: Experimental characterization of tilted waveguides.

From: Rotated waveplates in integrated waveguide optics

Figure 2

(a) End-view microscope images of waveguides (labelled 1–4) showing a progressive rotation of the cross-section as the offset d of the writing beam is increased. Scale bar, 5 μm. (b) Near-field profiles of the waveguide modes at different rotation angles. Quantitative measures are reported in Table 1.
